That's fine for new fonts, but it's not much help when using existing 
fonts.  Lilypond's Feta and those from Coda and Sibelius usually have a 
different range of glyphs from the Unicode set, so they can't be 
directly remapped.  For example they may have a combining flag symbol 
(a single flag that can be drawn as many times as required onto a note 
stem) instead of separate glyphs for 1, 2, 3, 4 or 5 -flag notes as in 
Unicode, and they often include single glyphs for things like mordents 
that are composite in the Unicode set.

A practical problem for people using Qt is that you can't address the 
musical symbols range at all using Qt's character class, which only 
supports UCS-2 (16 bits without surrogate pair support).  There's no 
way around that except to use something other than Qt for rendering.

(That's one reason Rosegarden uses Xft directly... that and a few other 
dumb things Qt does that make it really hard to use any font that 
doesn't have a full complement of latin1 symbols.)
